After Virtual Archaeology: Rethinking Archaeological Approaches to the Adoption of Digital Technology

open access: yesInternet Archaeology, 2017
In the 1980s archaeologists embraced the rapidly expanding field of computer modelling and visualisation as a vehicle for data exploration. Against this backdrop 'virtual archaeology' was conceived.

Hand-held Schlieren Photography with Light Field probes [PDF]

open access: yes, 2011
We introduce a new approach to capturing refraction in transparent media, which we call Light Field Background Oriented Schlieren Photography (LFBOS). By optically coding the locations and directions of light rays emerging from a light field probe, we ...

Reproduction Method of Rockfall Geologic Hazards Based on Oblique Photography and Three-Dimensional Discontinuous Deformation Analysis

open access: yesFrontiers in Earth Science, 2021
Rockfall geologic hazards are widely distributed. Due to their concealed nature, rockfalls are difficult to investigate using traditional contact survey methods, and the hazards they pose affect major projects and people’s safety.
